There are assembly facilities located underneath the old runway, and prototypical forms tested outside on the range are mounted on hydraulic pylons that rise out of the ground through doors in the runway surface. The facility is one of at least three Radar Cross-Section facilities owned by the major aerospace companies and located in the Antelope Valley area. It is at facilities such as this where stealth technologies, like the F-117 and B-2, and Joint Strike Fighter are developed.
